HARROW.

Speccaton of Letters Patent.

Patented Nov. 2'?, 1906.

Application led April 6,1906. Serial No. 310.278.

full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention has for its object to provide a simple, cheap, andeflicient harrow; and to this end it consists of the novel devices andcombinations of devices hereinafter descrih ed and specified in theclaim.

The invention is illustrated in the single view of the accompanyingdrawing, which view shows the improved harrow in plan.

Referring to the drawing, they numeral 1 indicates a drag-beam, which,as shown, is connected to a ring 2 by means of a pair ofpivotally-connected drag-bars 3. To the .drag-beam l is connected aplurality Of chains made up of rectangular links 4, the front links, asshown, being connected by rings 5 to staples 6, which latter are securedto the rear edge of said drag-beam l.

At suitable intervals of space the links of the parallel adjacent chainsare tied together or connected by rectangular links 4a, that are passedthrough the links which they connect in such manner that the said links4a are free to oscillate in vertical planes, thereby permitting theirprojecting angles to enter the ground to a considerable extent. Infact,all of thelinks 4 and 4tL are canted slightly or turned out ofhorizontal planes, so that certain of their projecting angles scrape thesurface Of the soil over which the harrow is drawn. The rearmost links 4of the longitudinallyextended chains at the extreme outer edges 0f theharrow interlock with the end links of the transverse chain which ismade up of the links 4, that are at the extreme rear portion of theharrow, so that there is provided, in eHect, a continuous chainfollowing a rectangular course along the sides and rear of 'the harrow.The rearmost links of the two outer chains are held spaced apart by aspacing-rod 7, and by this device several chains are held spread out, sothat their harrow will cover a considerable surface.

The ring 2 of course affords a device to which a suitable drive-link maybe attached for the purpose of drawing the harrow over the ground.

The harrow described, while Of small cost, is e'Hicient for the purposeshad in view, has no parts that are liable to get out of order, to wearout in any ordinary length of time, or to be broken.

What I claim io- In a harrow, the combination with a dragbar l, of aplurality of chains attached to said beam at their forward ends and madeup of rectangular links 4, intermediate rectangular links 4d interlockedwith and connecting alternately adjacent links Of the said parallelchains, and a spacing-rod 7 attached at its ends to the rearmost linksof the Outside chains, the most rearward links of the said outsidechains being interlocked with the end links of the chain made up of thelinks 4 that extend transversely at the rearmost portion of the harrow,substantially as described.

In testimony whereof I a'liix my signature in presence of two witnesses.
